Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an electronic golf swing training device that is worn on the body.

<Problems to be Solved by the Invention> Since golf practitioners cannot directly see their own golf swing form, they cannot directly check whether their own golf swing is appropriate.

Therefore, there is a need for a device that determines whether or not a golf swing is appropriate by detecting the golf swing position and measuring the swing time.

<Means for Solving the Problems> The electronic golf swing training device of the present invention includes a wristwatch type transmitter/receiver that detects the golf swing position, and a plurality of devices that are attached to predetermined positions on the clothes of the practitioner. The transmitter/receiver is composed of a repeater, and is characterized by having receiving means for receiving its own transmission signal via the repeater, and means for detecting a constant point of change in intensity of the received signal.

The constant point of change in intensity of the received signal refers to the maximum value at which the received signal changes from increasing to decreasing, and the unchanged state near the maximum value.

<Operation> When a practitioner uses the product of the present invention, the transmitter/receiver is attached to the left wrist, which is a relatively moving part of the body, and the receiver is attached to the buckle of the band of the pants, which is a relatively stationary part of the body. Attach a repeater near the abdomen (abdomen) and near the right shoulder (shoulder).

In the golf swing, in the address state, the signal strength of the received signal of the receiving part of the transceiver forms several maximum values or constant points. When the player starts the back swing, the signal strength of the received signal gradually weakens until it becomes impossible to receive the signal, but as the player approaches the top of the swing, the signal strength of the received signal gradually becomes stronger. When the top-of-swing condition is reached, the strength of the received signal forms a local maximum or a constant state. Next, when moving to the down swing state, the received signal changes inversely to the bank swing. Next, in the impact state, after the signal strength of the received signal becomes strong, a local maximum value is formed for a moment until the signal strength becomes weak. Therefore, by detecting changes in the signal strength of the received signal, the golf swing position and swing time can be accurately detected.

<Example> The present invention will be described below with reference to the drawings. However, golf practitioners must be right-handed. FIG. 1(a) is a diagonal diagram of a transmitter/receiver according to an embodiment of the present invention, and FIG. 1(b) is a diagram of FIG. 1(a).

FIG. 6(a) is a diagram showing the positional relationship between the address position indicating relay device 9a, the impact position indicating relay device 91, and the transceiver 1 in the address state and the impact state. When the relay device 9a and the relay device 91 are attached to a pants band or the like using pins 98, the light receiving element 91 and the light emitting element 92 will face downward at an angle of about 45 degrees with respect to the ground.

When the top-of-swing position relay device 9t is attached to clothing near the right shoulder using a pin 98, the light receiving element 91 and the light emitting element 92 will face upward at an angle of about 45 degrees with respect to the ground.

FIG. 7 is a block diagram of a repeater according to the present invention. The light receiving element 91 receives an optical signal from the transceiver 1 and converts it into an electrical signal. The AMP 931 amplifies the received signal, the filter 932 removes noise, the voltage conversion circuit 933 converts it to an appropriate voltage, and transmits it to the delay circuit 934. Delay circuit 934 delays the input signal by 1 bit, 2 bits, or 3 bits and outputs the delayed signal. The driver 935 amplifies the current,
The light emitting element 92 converts the electrical signal into an optical signal and transmits the optical signal. Therefore, the transmission signal is delayed by the setting value of the delay circuit with respect to the reception signal, and then optically transmitted. Delay circuits can be manufactured with high precision by combining monostable multi-by-breaks.

FIG. 8(a) is a block diagram of the transceiver 1 of the present invention. By operating the key 14, the program of the LSI 64 is set to the desired operating state.

The LSI 64 performs basic signal generation, input control, output control, and arithmetic control. When the LSI 64 outputs a transmission signal, the driver 65 amplifies the current, and the light emitting element 22 or 32 converts the electrical signal into an optical signal and transmits the optical signal. The light receiving element 21 or the light receiving element 31 receives an optical signal from the repeater and converts it into an electrical signal. The received signal strength detection section 60 amplifies the received signal, detects the signal strength of the received signal as an electrical quantity, and inputs it to the LSI 64. The LSI 64 drives the liquid crystal display element of the display section 5 and the piezoelectric ceramic element of the notification section 19 based on the calculation results.

FIG. 8(b) is a circuit block diagram showing one embodiment of the received signal strength detection section 60 of FIG. 7. Light receiving element 21 or 3
1 converts an optical signal into an electrical signal, and a first amplification section 601 amplifies the signal strength of the received signal to a detectable voltage level vQ. The second amplification section 602 performs voltage amplification and voltage level conversion up to the input voltage of the LSI 64, and inputs the signal Q to the LSI 64 when there is a received signal. When the LSI 64 receives the signal Q, it generates a received signal presence/absence notification signal Q1.

Further, the signal vQ from the first amplifying section 601 is sampled by the sampling section 603 at the time of the basic signal Ti. For example, in the top-op swing state, the signal vO is sampled for a time Ti=76, and if the signal vO is present at this time, the sampled signal VO is stored in the capacitor. Next, the peak detection unit 604 detects the peak voltage and stores the peak voltage v1 in the capacitor. If the received signal is received three times, the peak value voltage among them is stored. Next, the peak voltage is stored in the voltage first storage section 605. Next, the current received signal voltage level v1 in the first voltage storage section and the previous received signal voltage level v2 in the second voltage storage section are compared for a time corresponding to the voltage comparison signal from the LSI 64, and if Vl>V2. For example, the U signal of the Up detection unit 607 is set, and if vl<V2, the Down detection unit 60
If the D signal of 8 is set, V1=V2, and there is a received signal and the Q1 signal is set, the signal of the unchanged detection section 609 is set and input to the terminal X of the LSI 64.

Next, according to the voltage level storage signal M from the LSI 64,
The second voltage storage section stores the current signal voltage in a capacitor and sets it to voltage level v2. Also, the signal N of LSI64
This causes the storage capacitor in the peak detection section to be discharged and reset to a predetermined voltage.

On the other hand, the first voltage storage section 604 and the second voltage storage section 605
storage capacitor is stored when there is no received signal, i.e. Ql
When is being reset, the discharge is reset by the (TT/N) signal.

Incidentally, the received signal change detection sensitivity adjustment section 610 adjusts the minimum change voltage set by the Up detection section 607 and the Down detection section 608. That is, if the voltage change rate is a, it is set when vl< (1-a) ・v2, U is set when vl>(1+a) ・v2, and (1-a) ・v2≦v1 ≦(1+a) ・The time of v2 is a cent. If the voltage change rate a is made small, abnormal operation will occur due to camera shake, so it is necessary to set the voltage change rate to a value above a certain level that will not be affected by camera shake.

FIG. 9(a) is a circuit block diagram showing another embodiment of the received signal strength detection section 6o. In this embodiment, the signal strength of the received signal is detected by comparing discharge times. The light receiving element 21.31 converts the optical reception signal into an electrical signal, the first amplification section 601 amplifies the voltage, the second amplification section 602 further amplifies the signal, and the reception signal Q is input to the LSI. At the same time, the sampling unit 603 samples the received signal VO for a time Ti, for example, in the impact state, for a time Tf=73, and stores the voltage vO in the capacitor. next,
The peak detection unit 604 detects the peak value voltage v1 of the received signal.
is stored in the capacitor. Next, the storage capacitor of the peak value detection section 604 is discharged through the resistor by the discharge signal Nj of the LSI 64. Capacitor terminal voltage v2
When drops to a predetermined voltage, the comparator operates,
A signal P is generated and input to the LSI 64. The LSI 64 counts the time t from the start of the signal Nj until the signal P is detected, and detects a change in the signal strength of the received signal by comparing the discharge time t.

FIG. 9(b) shows a circuit diagram of the discharge voltage detection section 611.

When the FET 612 is turned on by the timing signal Tf, the capacitor C is charged to the output v1 of the peak detection section 604. Next, when the FET 612 is turned off and the transistor 613 is turned on at the same time, the charge in the capacitor C is discharged through the resistor R at a predetermined time constant. When the terminal voltage (2) of the capacitor C eventually decreases to the reference voltage (2)9, the comparator 614 detects this and outputs a signal P.

As yet another embodiment of the received signal strength detection section 60 of the present invention, a solid-state image sensor can be used.

FIG. 10(a) is an explanatory diagram of the operation of the solid-state image sensor in this embodiment. A shield 202 is installed on the top surface of the chip 201 of the solid-state image sensor 20 with a distance between the chips 201 and 201 of the solid-state image sensor 20 . Relay machine 9
(No. 3 is shielded by a shielding object 202, and a shadow of the signal occurs on the chip 201 of the solid-state image sensor 20, and there are parts that receive the received signal and parts that do not receive the received signal.This signal Each state of the golf swing can be determined by detecting when the shadow is at position A or B, when the shadow stops, and when the shadow is located at the center of the chip 201.

FIG. 10(b) is a circuit block diagram of a received signal detection method using a solid-state image sensor. The solid-state image sensor 20 is an LSI
After converting the optical reception signal into an electric signal in synchronization with the basic timing ti from 64 and amplifying it in an amplifying section 601, the reception position signal Pi is input to the LSI 64. Note that the 1.1 signals range from tl to tn (n is the number of pixels of the solid-state image sensor), and the signal Ti is composed of n t's. The LSI scans the number of pixels of the solid-state image sensor using signals from tl to tn. If you enter the shadow of the received signal during scanning, you will not be able to receive the received signal.
The golf swing position can be detected.

FIG. 11 is a diagram showing the relationship between the received signal strength and the golf swing state using the voltage comparison method shown in FIG. 8(b) or the discharge time comparison method shown in FIG. 9.

In the address state, the received signal fluctuates between strong and absent, and when entering the bank swing state, the received signal from the repeater attached to the abdomen decreases, but then the received signal from the repeater attached to the shoulder increases. Finally, it is in top swing condition. Next, as we move into the downswing state, the signal received by the repeater attached to the shoulder decreases, but then the signal received by the repeater attached to the abdomen increases, resulting in an impact state, and finally in the follow-through state. The received signal decreases and disappears.

The vicinity of the center of the chip 201 corresponds to the address state and the impact state. The edge of region A corresponds to the top-of-swing condition, and region B corresponds to the follow-through condition.

FIG. 13(a) is a time chart of the transmission signal of the present invention. The transmission signal of the transmitting/receiving unit 2 for address position detection and impact position detection of the transmitter/receiver 1 is 32, and the transmitter/receiver 1

shall be.

Basic timing of transmitter/receiver 1 from TO digit to T7
This basic timing is assigned to the above-mentioned transmission signal as follows.

TO=32 Transmitter/receiver transmits TI=Ra Address position detection signal T2 Not used.

T3=Ri Impact position detection signal and Wasoguru and swing discrimination signal T4=33 Transmitter/receiver transmits T5 Not used.

T6=Rt To7 swing position detection signal T7

The address position indicating relay device 9a transmits the transmission signal Ra with a delay of 1 bit/7 bits. The top-of-swing position indicating repeater 9t transmits the transmission signal Rt with a delay of 2b/).
Send. The impact position indicating relay device 91 transmits the transmission signal Ri with a delay of 3 bits.

In order to improve the transmission signal S2 and 53O3N ratio and reliability,
As shown in FIG. 13(b), for example, the signal is transmitted three times at 400 μs intervals, and when the signal is received two or more times, it is determined that the signal s2 or S has been received. The repetition interval is 5mS in the downswing state and impact state, and 20mS in the backswing state and toss-of-swing state.
Battery consumption is kept as low as possible by changing the time depending on the state, such as 50m5 in the address state and 1000mS in the standby state before the address.

FIG. 14 is a timing chart of the method of detecting the position of a received signal using a solid-state image sensor. The signals t1 to tn correspond to n pixels, for example, n-32 bits. This t. ~1. ．． constitutes one digit Ti.

FIG. 15 is a time chart of a method for detecting changes in signal strength of received signals by voltage comparison. In the figure, vl, v
The fact that a plurality of levels 2 are drawn indicates that the voltage level changes depending on the reception state.

FIG. 16 is a time chart of a method for detecting the signal strength of a received signal by comparing discharge voltage and time. In the figure, the first reception shows the case where the peak detection unit output v1 is large, and the second time shows the case where vl is small. Discharge time 1. ．． 12 is measured in the LSI.

FIG. 17 is a flowchart of a program according to an embodiment of the present invention. Between step 101 and step 103 is the standby state, between step 105 and step 106 is the address state, between step 106 and step 115 is the backswing state, between step 116 and step 117 is the toss-of-swing state, and step 124 and step 13
The period between steps 133 and 135 corresponds to a downswing state, and the period between steps 133 and 135 corresponds to an impact state. For example, in the vicinity of the tosobuob swing state, in step 110, the transceiver 1 transmits the signal S3, and in the next step 111, when it starts receiving the transmission signal Rt of ``it1m9t'', the up times signal t is set. The input X of the LSI starts receiving the Ut times signal, and the process moves from step 111 to step 114. Next, in step 114, the signal S3 is transmitted, and when the signal strength of the transmission signal Rt of the repeater 9t changes and approaches the top-of-swing state, an Up double signal t by the Rt double signal or a Down signal by the Rt double signal Dt is sent and steps 114 and 115 are repeated. Next, when entering the top-of-swing state, the left arm is momentarily stationary, so the signal strength of the received signal forms a local maximum value and does not change, and the signals Ut and Dt are not set in step 115, so the process proceeds to the next step 116. Move. If a signal is received in the swing state and both the signal Ut and the signal Dt are not set, the signal lt is set, so steps 117 and 116 are repeated.

Next, when the downswing starts, the Up times signal t or l
) own signal pt is sent, so the next step 1
Moving on to step 18, it is checked whether the top-of-swing time is zero. If so, a top of swing position error or overswing error handling routine is entered. ,
If the top-of-swing time has been measured in step 118, the process moves to step 124 and a down-swing time measurement routine is entered. Note that Da, Ua, and La are signals in the address state, Dt, Ut, and Lt are signals 1 in the top-of-swing state, and Dil Ui and Li are signals in the impact state. Also, B is a counter for measuring backswing time, T is a counter for measuring toss-of-swing time, D is a counter for measuring downswing time, and ■ is a counter for measuring impact time. In the step of outputting the transmission signal S2 or S, it is counted and amplified in step 1, and finally the time of each state is calculated from the count number.

<Effects of the Invention> According to the present invention, the device is composed of a wristwatch-type transmitter/receiver that is attached to the wrist and a repeater that is attached to clothes, etc. on the abdomen and shoulders, and detects a state where the magnitude of the received signal does not change momentarily. Since the address state, toss-of-swing state, and impact state are detected using the oscillator, the bank swing time, downswing time, etc. can be calculated and displayed with high precision. In addition, as mentioned above, the address state, swing of swing state, and impact state are detected by detecting the state where the magnitude of the received signal does not change momentarily. To prevent errors in detecting each state of a golf swing even if there is some variation in the golf swing.
